Application .lcd January 20, 1925.

This invention relates to copy holders, and especially an improvedcombination of typewriter-copy holder and line marker.

The main objects of this invention are to provide an exceedinglycapacious, strong, durable, elastic, convenient and thorough y practicaldevice for holding large and heavy books, las well as smaller ones andsingle 'sheets lto be copied from by a typist; to

A further object is to provide a device of this kind thatlhas uprightsor frame ele-v ments so constructed of ordinary mercantile stock, stripsor bars'ofv metal, that its lower part is relatively stiff and rigid,while its upper part has suflicient elasticity to avoid permanentdistortion of the device in the event a heavy book .is allowed to drop aslight distance onto the vcopy-seat.

Other objects and important features will `be pointed o ut oi implied inthe following details of descri tion, in connection with theaccompanying rawings in which:-

Fig. 1 is a front view of the device; Fig. 2 is a left-side view, thetypwriter-frame and copy-sheet being indicated in broken lines;

and F ig, 3 is-an enlarged detail view insection along the lines 3 3, 33, of Figs. l and 2. L

According to th embodimentifof the invention here shown, aboard orlbase-plate 5 is provided with grooves 6 in which are seated thelhorizontal parts ,7 of strips of,

steel or other metal whose upright parts S are riveted to or otherwise'rigidly united r with uprights 9 that are also formedof strips of`steel or other somewhat springy metal or material. The lower end of eachpart 9 extends horizontally forward'and is-` riveted or otherwiseVsecured to the, part v7, `as shown at 10, and the part 11 of each up-lright is forwardly and downwardly inclined from the part 8 to the part10 so as to `form a brace at the corner or angular bend where the parts7 and'S unite. Screws, as indicated, or other appropriate means may beemployed' for secpring the parts in the Serial No. 3,61%

The copy isvindicated at C as a single sheet-,but itis' obvious that a book oflarge size and'of more lthan Yaverage thickness can be placed; whileopen, between the4 parts 13 and 19,and that the latter will serve toprevent thebOOk-,leaves from swinging forward. f l;

19 and 20, Aasvdefined in the foregoin ,i they rigidly unite the pairsof strips, efined above, so they remain rigidlynnited even4 if the haseor plate 5 is detached or substituted by other means of securing thecopy seat in a definite relation to the typewriter.

Most all oi' the structure defined in the foregoing is described andclaimed in an application tiled by me on `or about the 15th day ofDecember, 1923, Serial No. 680,913, entitled Typewriter copy holder; andI will now give further details of the improvements which include theline marker, mentioned in the foregoing:

Guiding and scupporting strips 23 and 24 are preferably riveted orbolted to the parts 12 and 15, and have apertured ends extendinglaterally beyond the edges of the strips that support the copy-seat,their apertures 25a and 2la being rectangular or non-cylindrical andpreferably oblong. Through a pair of these apertures extends a compoundadjusting har 25, consisting of an intermediate part 25a, an upper endpart 25", and a lower end part 25, these latter parts extending at rightangles to and from opposite ends of the intermediate part, in oppositedirections, and lying in parallel planes. -The shape of this bar may bedefined either as a compound curve or a compound angle, so thenomenclature compound bar7 appears appropriate. The lower part 25c isserrated or provided with a series of evenly spaced notches at 26, thespaces or pitch of these notches being preferably equal to the singlespacing of an ordinary typewriter. These notches engage alternately oralternatively with the adjacent part of the bar 24, and a handle 27 isprovided on its lower end for ging these notches with the bar 3'-adjusting this bar for'properly 55s iing its arm or line-index 28 withi; to the copy C.

F0 properly adjusting the arm 28 with respejt to the different forms ofcopy, to-

wards' and from the plate 18, the index-arm or line-index may beangularly bent at 29, and its attaching end may be apertured andscrew-threaded at 30, to receive and mesh with an attaching andadjusting screw 31 having a knurled head or handle 32. The shank of thisscrew extends through an aperture of-the part 25a and works freely inthis aperture which. is not screw-threaded. lt will be s'een, therefore,that hy loosening the screw-,31, the arm 28 is freed so that it can bead usted to any of the positions shown in fu; and brokenlines and lto aninfinite number of other positions;'and that by tightening the screw,the arm 28 is secured in angl one of its adjustedpositions.

Al ough the inclined position of the part rect-ion, tend to utilize the.force of gravity for holding the respective notches 26 in iengagementwith the bar 24, and although it is within the scope olf-this inventionto change the shape of eac-hnotch so that such engagement willetl'ectually be retained until the bar is manually moved for disengagingthese parts and changing the adjustments ot the bar and its arm 28, itmay be of advantage to provide a springfor yieldingly retaining theengagement of these parts, and such a spring is indicated at 83 of Fig.3, being omitted in the other ligures of the drawings.

For use in connection with certain types of typewriters, it may bedesirable to operate the line-marker with the left hand, instead of theright, and in such event, the bar 25l may be transferred from thepositionshown to the apertured parts 23*1 and 2f'at the left side of thedevice, and the arm 28 may be transferred from the left side to theright side of the bar25. One or more rollers (not shown) may bejournalled on the arm 28 for rolling on the copy or on the plate 18.

In operating the line marker when the copy C is on lthe copy-seat, theindex-arm 28 is first adjusted so it lies near the copy and just belowthe first line to be copied from, and when through with thisline, theoperator grasps the handle 27 and pulls it forward, then allows it todescend until the index-arm is just below the next succeeding line, thenengages the notched part 26 with the bar 24 for holding the line-markerin position; and this operation is repeated until all the lines havebeen successively marked and copied or copied from.

It is not intended to limit my patent protection to the exact details ofconstruction and arrangement here shown, but the invent-ive ideaincludes analogous devices within the scope of the claims.

lVhat I claim as my invention is:

1. A copy holder which includes two spaced pairs of relatively thin andwide springy strips, the strips of each pair having their wide sidesconfronting one another, a horizontal plate to be seated on a table andto extend under a typewriter, a copy-holding plate, and means securingthe copy-holding plate to the spaced pairs of strips over saidhorizontal plate, said strips of each pair including horizontallyextending parts which are superposed upon one another and upon said Ihorizontal plate. and secured to the latter, said strips havingjuxtaposed parts fixedly secured to one another at points above saidhorizontal plate and thus forming relatively stiff upright supportingpart-s, the parts of saidstrips which extend up from .said stiffupright. parts to said copy-holding plate being, forwardly anddownwardly 24, and ofthe part 2.5 inthe opposite'di-A bowed and s pacedfrom one another to provide aspringy support for said copy-holdingplate. Y

2. The combination of a eopyseat including an upright part againstwhichthe back ,of a copy cane-rest, a supporting structure melding theeo yseat in position tu permit, a typewriter to e positioned undef thecopyv seat, this supporting structure inciuding apertured elements, abar including n ser mated part and being sldable u :and down in :leidniieituwd elements ami] mijustisbie te fiitwr'm; pueitiuia byinterchangeable engagemem iii the seimtions with one 0f said apei'turedelements, and a line-index arm carried by said bar, substantially asshown, for the purpose Specified.

3. The structure defined by claim Q, said -arm being adjustable towardsand from said upright part, and manipulative means to secure said arm inits dierent adjust- .e
